The DTO.class :

package com.milkmantechnologies.ems.dto;

import lombok.extern.slf4j.Slf4j;

@Slf4j
public abstract class DTO<T, ID_> {

    public abstract ID_ getId();

    public abstract T to();

    public abstract DTO<T, ID_> from(T t);

    public static <T, ID_, Q extends DTO<T, ID_>> Q from(T t, Class<Q> clazz) {
        Q result = null;
        try {
            result = (Q) clazz.getDeclaredConstructor().newInstance().from(t);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
        return result;
    }
}

Hey @roberto-perata! The error likely goes away when you drop the unused @Slf4j annotation. See #1250.

[roberto-perata]

it's correct, thank you
